DxChartFinancialReduction Class

Specifies reduction properties for financial series.

Assembly: DevExpress.Blazor.v23.2.dll

Declaration

public class DxChartFinancialReduction :
    DxSettingsComponent<ChartFinancialReductionModel>

Remarks

The DxChart component compares each point in a financial series to the previous point. You can use the DxChartFinancialReduction object to highlight points where values decreases.

The following properties are available:

Color: Specifies the color for financial series points whose values are lower than in their previous points.
Level: Specifies which values of financial series points stock are compared.

The following example uses a radio group to switch between reduction levels and changes the color of series points with a lower price:

    <label>Reduction Level:</label>
    <DxRadioGroup Items="@(Enum.GetValues(typeof(ChartFinancialReductionLevel)).Cast<ChartFinancialReductionLevel>())"
                  @bind-Value="@ReductionLevel" />
</div>
